ELLIOT, Polly and George W. Briggs, April 2, 1820.
"Sons of John Briggs of Taunton, Massachusetts", NEHGR, p. 126:37, adds daughter "?Sophia". It does not explain what this is based on and no evidence is found in the expected places.
↑ Note: familysearch.org shows a date of 26 Feb 1820. The film number cited (721190) is "Births, marriages and intentions, deaths, ca. 1710-1877 (Sutton, Massachusetts)". This is undoubtedly the date intentions were published, superseded in the published VRs by the marriage record..
